اثر سطوح مختلف پروتئین جیره بر شاخص های رشد ماهی اسکار (Astronotus ocellatus, Agassiz, 1831)
آزمایشی جهت تعیین میزان پروتئین بهینه جیره غذایی ماهی اسکار (Astronotus ocellatus) طراحی شد. ماهیان با چهار نوع جیره غذایی با میزان کالری یکسان و با میزان پروتئین 40، 45، 50 و 55 درصد به مدت 8 هفته تغذیه شدند. کم ترین و بیش ترین افزایش وزن به ترتیب در ماهیان تغذیه شده با جیره 40 و 50 درصد پروتئین مشاهده شد. تنها اختلاف معنی داری در افزایش وزن ماهیان تغذیه شده با جیره 40 ...
متن کاملA new species of Tripartiella (Ciliophora: Trichodinidae) from Aequidens tetramerus (Perciformes: Cichlidae) in north Brazil.
A new species of Tripartiella is described from the gills of the wild saddle cichlid Aequidens tetramerus in north Brazil. Wet smears of skin and gills of examined fish were air-dried at room temperature and impregnated with Klein's dry silver method for examination of the adhesive disc's structures and denticles. Total prevalence of parasitism was 65%. This ciliate is characterized as a small-...
متن کاملDevelopment of Procamallanus saccobranchi (Nematoda: Camallanidae), a parasite of a freshwater fish in India.
The development of the nematode Procamallanus saccobranchi Karve, 1952, a parasite in the stomach of the fish Heteropneustes fossilis (Bloch), was studied in Mesocyclops crassus (Fischer) and Mesocyclops leuckarti (Claus). After being ingested by the copepods the nematode first-stage larvae penetrated into the haemocoel of the intermediate host; there they moulted twice (on days 3 and 5 p.i. at...
متن کاملNew morphological data on the first-stage larvae of two Procamallanus species (Nematoda: Camallanidae) based on SEM studies.
First-stage larvae of camallanid nematodes Procamallanus (Procamallanus) laeviconchus (Wedl, 1862) and Procamallanus (Procamallanus) sp. from naturally infected Distichodus niloticus (Hasselquist) and Clarias gariepinus (Burchell), respectively, from Lake Turkana, Kenya (new geographical records) are described, being for the first time studied by scanning electron microscopy. Larvae of both spe...
متن کاملExpanded description of Lamproglena monodi (Copepoda: Lernaeidae), parasitizing native and introduced fishes in Brazil.
An occurrence of the copepod Lamproglena monodi Capart, 1944, parasitizing freshwater fishes in Brazil is presented, along with new morphological data. This crustacean was originally described parasitizing several cichlids in Africa. In the present study, the crustaceans were collected from the body surface and gills of two fish species native to Brazil [Astronotus ocellatus (Agassiz, 1831) and...
